Pacemaker syndrome caused syncope during defecation in a patient with complete heart block. Adjusting pacemaker settings and addressing contributing factors resolved the episodes.

Area of Science:

  • Cardiology
  • Electrophysiology
  • Medical Case Reports

Background:

  • A VVI pacemaker was implanted in a 73-year-old female for complete heart block.
  • The patient experienced recurrent episodes of syncope, specifically defecation syncope.

Observation:

  • Hemodynamic investigations revealed an abnormal blood pressure drop during the overshoot phase of the Valsalva maneuver.
  • This was associated with alternating sinus and pacemaker rhythms, indicative of pacemaker syndrome.

Findings:

  • The modified Valsalva response, exacerbated by hypovolemia and nitroglycerin, manifested as defecation syncope.
  • Treatment involved eliminating contributing factors and programming a lower pacemaker frequency to prevent sinus-pacemaker alternations.

Implications:

Related Experiment Videos

  • This case highlights the potential for pacemaker syndrome to manifest during defecation.
  • Management requires identifying and addressing contributing factors alongside pacemaker programming adjustments.
